Electronic Data Interchange Software consists of the following four layers :

  • A.Business application, Internal format conversion, Network translator, EDI envelope
  • B.Business application, Internal format conversion, EDI translator, EDI envelope
  • C.Application layer, Transport layer, EDI translator, EDI envelope
  • D.Application layer, Transport layer, IP layer, EDI envelope

Answer: B

EDI software consists of four layers: the business application, the internal format conversion, the EDI translator and the EDI envelope. The application produces the data, the conversion layer turns it into an intermediate form, the translator converts it to the EDI standard format and the envelope wraps it for transmission.

The option with a 'network translator' is not an EDI term. The remaining two options mix in transport and IP layers, which belong to the network protocol stack and not to EDI software.
